A comparative study to evaluate the cervical spine movements during laryngoscopy using Macintosh and Airtraq laryngoscopes.

Background and Aim: Intubation with Macintosh requires flexing the lower cervical spine and extending the atlanto-occipital joint to create a "line of sight." Primary aim of study was to compare the extent of cervical spine movement during laryngoscopy using conventional Macintosh laryngoscope and Airtraq. Material and Methods: A total of 25 patients of either sex between the age group of 18 and 60 years, having American Society of Anesthesiologists (ASA) physical status of Grade-I and Grade-II, scheduled for elective surgery under image control requiring general anesthesia and intubation were enrolled. A baseline image of the lateral cervical spine including the first four cervical vertebrae was taken by an image intensifier. After administration of general anesthesia, laryngoscopy was first performed using a Macintosh laryngoscope and a second X-ray image of the lateral cervical spine was taken. The second laryngoscopy using a Airtraq laryngoscope was done and the third image of the lateral cervical spine was taken. Angles between occiput and C1; C1 and C2; C2 and C3; C3 and C4; and occiput and C4 were calculated. Atlanto-occipital distance (AOD) was calculated as the distance between occiput and C1. Results: Macintosh showed greater cervical movement as compared with Airtraq but a significant difference in the movement was observed at C2-C3 and C0-C4. Baseline mean AOD was 2.21 ± 1.25 mm, after Macintosh and Airtraq laryngoscopy was found to be 1.13 ± 0.60 and 1.6 ± 0.78 mm, respectively, and was found to be significant (P < 0.05). Conclusion: We conclude that Airtraq allows intubation with less movement of the upper cervical spine makes Airtraq preferred equipment for intubation in patients with a potential cervical spine injury.

Neglected extensive Aspergillus osteomyelitis of the pelvis, femur, and vertebra in an immunocompetent patient: A case report.

De novo Aspergillus infections of the appendicular skeleton are rare. A 72-year-old female presented with pain and deformity in her left lower limb and an inability to bear weight that had persisted for the last six months. A femur biopsy confirmed the diagnosis of extensive Aspergillus osteomyelitis, and the patient was treated with amphotericin B and oral voriconazole. The patient died of COVID-19 after 2.5 months of treatment. A diagnosis of Aspergillus osteomyelitis may be delayed because of its varied clinical presentation. To the best of our knowledge, this is the first known case of de novo neglected and extensive (multisite, multibone) Aspergillus osteomyelitis in an immunocompetent patient. This case highlights the importance of awareness in patients and treating physicians of this rare infection and its early diagnosis to prevent extensive spread.

How Not To Fix a Tibial Fracture: A Case Report on Treatment By a Quack.

Quackery in the orthopaedic profession has existed for quite a long time. Due to the shortage of orthopaedic healthcare staff in public hospitals and the high costs in private facilities, members of disadvantaged communities turn to unlicensed and unskilled practitioners (quacks). The main factors responsible for the increased number of quacks performing orthopaedic treatment are illiteracy, high treatment cost, mismatch in the orthopaedic surgeon-to-population ratio, especially in rural areas, and the absence of any form of health insurance. Moreover, their easy availability and offer of low-cost treatment draw innocent and illiterate patients to them, even though these quacks perform orthopaedic treatment in the most unhygienic, unsterilized, and unconventional manner. The government should intervene and take measures to make orthopaedic treatment more affordable and accessible, especially to the rural population.

A Prospective Study to Evaluate the Clinical and Diffusion Tensor Imaging (DTI) Correlation in Patients with Lumbar Disc Herniation with Radiculopathy.

Introduction: Conventional magnetic resonance imaging findings frequently do not correlate with the symptoms of lumbar disc herniation (LDH). Diffusion-weighted imaging can reveal important details about the microstructure of tissues. This study assessed the role of diffusion-weighted imaging (DTI) in LDH with radiculopathy and explored the relationship between DTI values and clinical scores. Methods: Forty-five patients with LDH with radiculopathy were evaluated via DTI at the intraspinal (IS), intraforaminal (IF), and extraforaminal (EF) levels. A visual analog scale (VAS) was used for low back and leg pain. The Japanese Orthopaedic Association (JOA) scoring system, Oswestry Disability Index (ODI), and Roland-Morris Disability Questionnaire (RMDQ) were used for functional evaluation. Results: There was a statistically significantly (p<0.05) difference between the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values on the affected side compared with those on contralateral normal side. The VAS score had a weak positive correlation with RMDQ score (r=0.279, P=0.050). The JOA score had a moderate negative correlation with RMDQ score (r=-0.428, P=0.002), whereas the ODI score had a moderate positive correlation with RMDQ score (r=0.554, P<0.001). There was a moderate positive correlation between ADC values at the IF level and the RMDQ score on the affected side (r=0.310, P=0.029). There was no correlation between FA values and JOA score. ODI had a significantly positive correlation with the contralateral normal side FA values at the IF (r=0.399, P=0.015), EF (r=0.368, P=0.008) and IS (r=0.343, P=0.015) levels. RMDQ had a weak positive correlation with the contralateral normal side FA values at the IF (r=0.311, P=0.028), IS (r=0.297, P=0.036) and EF (r=0.297, P=0.036) levels. Conclusions: The decrease in FA values and the increase in ADC values are useful markers of compression. ADC correlates well with the patient's neurological symptoms and functional status. Conversely, FA correlates well with the patient's neurological symptoms, but is not correlated well with the functional status.

Report of a Rare Case of Pubic Symphysis Tuberculosis in an Eight-Year-Old Child: An Unusual Presentation of the Disease.

Tuberculosis is a well-known and ancient disease with a wide range of clinical presentations. Although tuberculosis is a well-known infectious disease, involvement of the symphysis pubis is rare, with only a few documented cases in the medical literature. Distinguishing it from other more common conditions, such as osteomyelitis of the pubic symphysis and osteitis pubis, is essential to avoid delay in diagnosis and to minimize morbidity, mortality, and complications. We present a rare case of tuberculosis of the symphysis pubis in an eight-year-old female from India who was initially misdiagnosed with osteomyelitis. Following the correct diagnosis and commencement of anti-tuberculosis chemotherapy, the patient demonstrated improvement in symptoms and hematological parameters at the three-month follow-up. This case emphasizes the importance of considering tuberculosis as a differential diagnosis in cases of symphysis pubis involvement, especially in areas with a high incidence of tuberculosis. Early diagnosis and appropriate treatment can prevent further complications and improve clinical outcomes.

Do MRI-derived muscle moment-arms in patients with chronic low back pain differ from healthy individuals? A comparative study.

OBJECTIVES: The present study aimed to estimate the trunk muscles moment-arms in low back pain (LBP) patients and compare this data to those of healthy individuals. This research further explored whether the difference of the moment-arms between these two is a contributing factor to LBP. METHODOLOGY: Fifty patients with CLBP (group A) and 25 healthy controls (group B) were enrolled. All participants were subjected to magnetic resonance imaging of lumbar spine. Muscle moment-arms were estimated on a T2W axial section parallel to the disc. RESULTS: There was statistically significant differences (p < 0.05) in the sagittal plane moment-arms at L1-L2 for right erector spinae (ES), bilateral psoas and rectus abdominis (RA), right quadratus lumborum (QL), and left obliques; bilateral ES, QL, RA, and right psoas at L2-L3; bilateral QL, RA, and obliques at L3-L4; bilateral RA and obliques at L4-L5; and bilateral psoas, RA, and obliques at L5-S1. There was no statistically significant difference (p < 0.05) in the coronal plane moment-arms except for left ES and QL at L1-L2; left QL and right RA at L3-L4; right RA and obliques at L4-L5; and bilateral ES and right RA at L5-S1. CONCLUSIONS: There was a significant difference in muscle moment-arms of the lumbar spine's prime stabilizer (psoas) and primary locomotors (rectus abdominis and obliques) between LBP patients and healthy individuals. This difference in the moment-arms leads to altered compressive forces at intervertebral discs and may be one of the risk factors for LBP.

Outcome of monolateral rail fixator in infected nonunion of femur diaphysis developing after intramedullary fixation.

INTRODUCTION: Consensus is lacking regarding management of posttraumatic infected diaphyseal nonunions of femur following intramedullary nailing. Present study reports outcomes of single stage standardised treatment protocol using monolateral rail external fixator/limb reconstruction system in this type of infected diaphyseal femoral nonunions. METHODS: This retrospective study included 26 patients with mean age of 31.7 years having posttraumatic infected diaphyseal femoral nonunions following intramedullary nailing and managed with radical debridement and monolateral rail fixator. The results were assessed by Association for the Study and Application of the Method of Ilizarov criteria. RESULTS: Mean intraoperative bone gap was 4.34 (range, 2-7) cm. Mean gain in bone length was 4.04 (range, 0-7) cm. Fracture united primarily in 22 cases and after freshening of edges, fixator adjustment and fibular grafting in three more patients. Infection persisted in one patient. Most common complications were superficial pin tract infection (15 patients) and loss of more than 30° knee flexion (13 patients). The bone results were excellent, good, and poor in 15, 9, and 2 patients, respectively. The functional results were excellent, good, fair, and poor in 11,13,1 and 1 patient, respectively. CONCLUSION: Single stage procedure including radical debridement, acute docking, distraction osteogenesis at corticotomy site and stabilization with monolateral rail fixator reliably achieves good to excellent bone and functional results, union and eradication of infection in majority of infected nonunions of femoral diaphysis developing after intramedullary fixation. We recommend acute docking in bone gap ≤ 5 cm.

Functional and radiological outcomes of primary ring fixator versus antibiotic nail in open tibial diaphyseal fractures: A prospective study.

BACKGROUND: Management of open fractures of tibia is still a matter of debate due to high incidence of infections. Traditionally external fixators have been advocated in managing open tibial fractures. Due to limited efficacy of systemic antibiotics, recently antibiotic coated intramedullary interlocking nails have been developed for the management of open tibia fractures. Therefore, we conducted this prospective randomized study to compare the functional and radiological outcomes of primary ring fixator versus antibiotic coated nail in open diaphyseal tibial fractures. METHODS: The study included 32 patients with Gustilo-Anderson type II and type IIIA fractures of tibial diaphysis. Out of them 16 patients were managed with Ring External Fixator (Group I) and 16 were managed with OssiproÒ gentamicin intramedullary interlocking tibial nail (Group II). The radiological and functional outcomes were assessed at final follow-up according to and SMFA criteria. Statistical analysis of the data was performed using IBM SPSS statistics 2.0 software. Chi square test and independent student t-test were used and a P value <0.05 was considered statistically significant RESULTS: Union was achieved in 15 patients (93.8%) in group I and 13 patients (81.2%) in group II. Pin tract infection was seen in 6 patients (37.5%) in group I, whereas infection was present in 2 patients (12.5%) in group II. Bone results were excellent in 13 patients (81.3%), good in 2 patients (12.5%), poor in one patient (6.3%). In group II, bone results were excellent in 12 patients (75%), good in one patient (6.2%), poor in 3 patients (18.8%). At 1 year of final follow up, mean SMFA score was 24.41±5.87 in group I, whereas mean SMFA score was 23.703±8.02 in group II. CONCLUSION: Ring fixator as well as antibiotic coated tibial interlocking nail achieved comparable rates of union in the present study. Complication rates were similar in both the groups and the functional and radiological outcomes were comparable in both groups. Results of this study indicate that although ring fixation is an established option for management of open tibial fractures, antibiotic-coated intramedullary nail is also a reliable option in open Grade II and grade IIIA injuries. LEVEL OF EVIDENCE: Level II.

Prospective randomized comparison of bone transport versus Masquelet technique in infected gap nonunion of tibia.

AIM: The present prospective randomized study compared the bone transport technique (BT) and Masquelet technique (MT) in the treatment of infected gap non-union of the tibia. PATIENTS AND METHODS: Total 25 patients with infected gap non-union of the tibia with bone gap upto 6 cm were randomised into BT group (group I, 13 patients) and MT (group II, 12 patients). The mean age was 31.77 years in group I and 39.67 years in group II. The mean intra-operative bone gap was 3.92 cm in group I and 3.79 cm in group II. Monolateral fixator was applied in nine patients each in both groups, while four and three fractures were stabilized with ring fixators in group I and II, respectively. Mean follow-up was 31.62 months and 30.42 months in group I and II, respectively. Bone and functional results were compared using the association for the study and application of the method of Ilizarov (ASAMI) criteria. RESULTS: The average fixator period was 9.42 and 16.33 months in group I and II, respectively (p < 0.001). Union was achieved in 12 (92%) patients and 6 (50%) patients in group I and II, respectively. The functional results were excellent (eight and two), good (four and six), fair (zero and three) and poor (one and one) in group I and II respectively, (p 0.23). The Bone results were excellent, good and poor in nine, three and one patients in group I, and three, three and six patients in group II respectively, (p 0.109). CONCLUSIONS: The functional and bone results were comparable but more reliable in bone transport than the Masquelet technique. The fixator duration and incidence of non-union were higher in MT group. Ilizarov bone transport technique should be preferred in infected non-union of the tibia with bone loss upto 6 cm.

A study to evaluate ocular changes in patients undergoing spine surgery in the prone position.

Background and Aims: AA present prospective study was conducted to evaluate ocular changes occurring in patients undergoing spine surgery in the prone position. Material and Methods: A total of 44 patients of either sex, belonging to American society of Anaesthesiology I and II (aged 18-60 years) scheduled for elective spine surgery in prone position were enrolled in the study. Baseline IOP and MAP measurement were taken prior to induction. After induction of anaesthesia patients were intubated using flexo-metallic tube of appropriate size. IOP and MAP were recorded after induction of anaesthesia, following completion of surgery and immediately after turning the patient supine and 30 min following extubation. Blood loss and duration of surgery was also noted. The OPP was derived using the formula (OPP = MAP-IOP). Ophthalmic examination was also performed using direct and indirect ophthalmoscopy on the day prior to surgery and on first post-operative day to rule out anterior ischemic optic neuropathy (AION), posterior ischemic optic neuropathy (PION), and retinal ischemia. Results: Mean IOP significantly increased (18.91 ± 3.56 mm Hg) (P < 0.001) at the end of surgery as compared to baseline value 12.85 ± 3.07 mm Hg. As a result mean OPP significantly reduced (75.12 ± 16.45) (P = 0.0018) at the end of the procedure. Conclusion: In patient's undergoing spine surgery in the prone position, careful patient positioning with no extrinsic pressure on the eyes, minimal surgical time and blood loss, and prevention of intraoperative hypotension, should be ensured to prevent the IOP rise and a reduction in OPP which can further prevent post-operative visual disturbance.

Correlation of Clinical Findings in Acute Spinal Injury Patients with Magnetic Resonance Including Diffusion Tensor Imaging and Fiber Tractography.

INTRODUCTION: Many types of research are being carried out in the fields of understanding of the pathogenesis, early recognition, and improving the outcomes after spinal cord injury (SCI). Diffusion tensor imaging (DTI) is one of the modalities used in vivo microstructural assessment of SCI. The aim of the present study is to evaluate the role of DTI imaging and fiber tractography in acute spinal injury with clinical profile and neurological outcome. METHODS: The study was carried out on twenty-five patients of acute spinal cord injury who presented within 48 hours of injury and completed minimum of six months follow-up. RESULTS: The mean age of patients was 37.32±13.31 years and male & female ratio of 18:7. Total MIS score was 91.64±6.0 initially which improved to 96.92±3.68 after 3 months and 99.4±1.35 after 6 months. Total SIS score was similar at all the time intervals i.e. 224±0. Maximum subjects 14(56%) were classified into AIS C and 5(20%) into AIS D whereas only 6(24%) subjects were having no deficit (AIS E). At the end of 6 months, 13(52%) subjects had no deficit (AIS E). Mean fractional anisotropy (FA) initially was 0.451 (± 0.120) but after 6 months, it increased to 0.482 (± 0.097) (p<0.001). The mean apparent diffusion coefficient (ADC) initially was 3.13 (± 2.68) but after 6 months, it decreased to 3.06 (± 2.68) and this change was found to be statistically highly significant (p<0.001). Mean anisotropy index (AI) initially was 0.420 (± 0.245) but after 6 months, it increased to 0.430 (± 3.41) and this change was found to be statistically significant (p<0.01). CONCLUSIONS: DTI is a sensitive tool to detect neurological damage in SCI and subsequent neurological recovery. FA correlated with ASIA impairment scale. It can be useful as an adjunct to conventional MRI for better evaluation and predicting prognosis in SCI patients.

Giant Ganglion Cyst of the Proximal Tibiofibular Joint with Peroneal Nerve Palsy: A Case Report.

INTRODUCTION: Ganglion cysts are benign cystic tumors of musculoskeletal structures which have variable clinical presentations, however, compression neuropathies due to ganglion cyst are much less common in the lower extremity and only a couple of cases have been described in the literature. Hence, in the current case report, we describe a patient with a giant ganglion cyst causing peroneal nerve palsy which was managed surgically. CASE REPORT: A 50-year-old female presented with a 2-month history of progressive left foot drop with a gradual development of swelling over the left fibular head. Imaging suggested ganglion cyst-induced peroneal nerve palsy. Initial conservative treatment failure warranted surgical excision which confirmed extraneural origin on histopathological examination. An immediate clinical improvement was observed postoperatively and full recovery occurred within 6 months. There was no recurrence at 2 years follow up. CONCLUSION: The ganglion cyst-induced compression neuropathies are uncommon in lower limbs, especially in a skeletally mature person. Our case was an extraneural cyst which is the rare comparatively. The possibilities of other differentials should be excluded through imaging due to non-specific presentations. Surgical management is the preferred mode of treatment with 10% recurrences which can be reduced by complete excision including stalk.

Electrophysiological Study in Acute Spinal Cord Injury Patients: Its Correlation to Neurological Deficit and Subsequent Recovery Assessment by ASIA Score.

BACKGROUND: To investigate the relationship between neurological deficit and subsequent recovery as assessed by ASIA score and findings of electrodiagnostic study in acute spinal cord injury (SCI) patients. METHODS: Thirty-five patients with acute SCI presenting within 48 h of injury were clinically evaluated for the level, extent, and severity of SCI according to the ASIA standards in a tertiary-level care center. Electrodiagnostic studies of bilateral two motor (tibial and peroneal), one sensory (sural) nerves, and five muscles [iliopsoas, vastus medialis, tibialis anterior, gastrocnemius, and extensor hallucis longus (EHL)] were conducted and repeated at 3 months and 6 months. RESULTS: The neurological recovery was highly significant (p < 0.001) at 6 months. The difference in mean amplitude was statistically significant (p < 0.05) for all the nerves; mean conduction velocity significant for peroneal and sural nerves, and with no significant difference in mean latency. The differences in mean recruitment of motor unit potential (MUP) and mean peak-to-peak amplitude were highly significant (p < 0.001). Statistically significant kappa agreement between neurological recovery according to ASIA score and nerve conduction velocity was found for right tibial nerve (K = 0.324); electromyography finding of recruitment of MUP with right and left tibialis anterior (k = 0.400) and left EHL (k = 0.407); peak-to-peak amplitude with right tibialis anterior (k = 0.211), right gastrocnemius (k = 0.390), and right EHL (k = 0.211). CONCLUSIONS: There is a strong relationship between electrodiagnostic findings and ASIA scoring to predict neurological deficit and subsequent recovery after acute traumatic SCI. Serial neurologic evaluation by ASIA score and electrodiagnostic studies may help in designing customized rehabilitation programs for the patients according to the expected neurological recovery; and evaluating future research in the field of SCI with more scientific authenticity.

Comparison of Clinico-radiological Outcomes of Monolateral Fixator in Infected Non-union of Tibia Based on Bone Gap Quantification.

INTRODUCTION: Monolateral rail fixators are more comfortable to the patients and have a lesser learning curve compared to ring fixators. Guidelines are still lacking for rational use of monolateral fixator for bone transport. This retrospective study aimed to analyze and compare the clinico-radiological outcomes of monolateral fixator in infected non union of tibia based on bone gap quantification. MATERIALS AND METHODS: This retrospective study included 35 patients of post traumatic infected osteocutaneous defects of tibia operated from May 2013 to May 2016. Group I having bone gap of 6 cm or less (n = 20) and group II with > 6 cm bone gap (n = 15). The mean age was 29.56 (range 18-62) years in group I and 29.67 (range 20-65) years in group II. The mean bone gap was 4.62 (2-6 cm) in group I and 7.6 cm (6.5-10 cm) in group II (P < 0.00001, Mann-Whitney test). The results were assessed by Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria. RESULTS: Union was achieved primarily in 90% (n = 18) cases in group I and 73.34% (n = 11) cases in group II. The bone result was excellent, good, fair/poor in 14, 5, 1 in group I; and in 4, 6, 5 in group II, respectively (P = 0.020, Chi-square test). The functional results were excellent, good, fair/poor in 15, 4, 1 in group I; and 5, 8, 2 in group II, respectively (P = 0.0479, Chi-square test). CONCLUSION: We recommend use of monolateral fixator in patients with infected diaphyseal non union of tibia with bone gap ≤ 6 cm. Use of monolateral fixator in patients with bone gap > 6 cm is associated with higher incidence of residual problems and complications.

Magnetic Resonance Imaging of Trunk Musculature and Intervertebral Discs in Patients with Spinal Cord Injury with Thoracolumbar Vertebral Fractures: A Prospective Study.

STUDY DESIGN: This study is a prospective clinical study. PURPOSE: This study aims to evaluate the characteristics of trunk musculature and intervertebral discs by using magnetic resonance imaging in patients with spinal cord injuries (SCIs) with thoracic and lumbar fractures. OVERVIEW OF LITERATURE: Muscle atrophy is an immediate consequence of SCI and is associated with secondary complications. At present, there are limited clinical data on muscle and disc responses to fractures of the thoracic and lumbar spine. METHODS: A total of 51 patients with a mean age of 31.75±10.42 years who suffered traumatic SCI were included in this study. Complete neurological examinations (American Spinal Injury Association grading) and magnetic resonance imaging (MRI) were performed at the time of admission and at 3-6 months after injury to study the neurological status and disc and trunk parameters. The type of management (operative or conservative) was decided on the basis of clinical, radiological, and MRI evaluations, and a robust rehabilitation program was initiated. RESULTS: Disc parameters including disc angle, skin angle, cross-sectional area (CSA), and disc height and trunk parameters (mean trunk width, mean trunk depth, and CSA of the lumbar muscles) decreased significantly (p <0.001) during the first 3 months after SCI. However, improvements were observed in disc and muscle parameters at the 6-month follow-up, but these parameters did not return to normal levels. Neither initial neurological status (complete vs. incomplete) nor type of management (operative vs. conservative) had a significant effect on these parameters. CONCLUSIONS: Spinal trauma leads to alterations in the morphology of the vertebral column, spinal cord, intervertebral discs, and paraspinal muscles in the initial phase of injury. The extent of these changes may determine the initial neurological deficit and subsequent recovery. Although this study did not identify any statistically significant effect of neurological status or management strategy on these parameters, rehabilitation was found to result in the improvement of these parameters in the later phase of recovery. Future studies are required to evaluate the exact causes of these alterations and the potential benefits of rehabilitation strategies and to minimize these changes.

Comparative study of medial opening wedge high tibial osteotomy using fixator-cum-distractor device or locking plate in medial unicompartmental osteoarthritis of knee.

OBJECTIVE: The aim of our study was to evaluate the role of medial opening wedge high tibial osteotomy (MOWHTO) in medial unicompartmental osteoarthritis of the knee and compare two different fixation devices for stability, duration, outcome, and complications. METHODS: Fifty-seven patients (60 knees) of age < 60 yrs and either sex with medial unicompartmental osteoarthritis of the knee were divided into 2 groups. Twenty-four patients (25 knees) in Group I underwent MOWHTO using fixator-cum-distractor and 33 patients (35 knees) in Group II underwent MOWHTO using locking plate osteosynthesis. The results were assessed by VAS, KOOS and WOMAC score. RESULTS: Mean age of the patients in Group I was 53.13 ±â€¯5.20 years and 51.32 ±â€¯6.91 years in Group II. Mean preoperative varus deviation was 11.97 ±â€¯3.34° in Group I and 11.78 ±â€¯3.05° in Group II which was corrected to 3.27 ±â€¯1.75° and 3.56 ±â€¯1.47° valgus respectively. All the patients achieved full weight bearing by 35th day postoperatively in Group I with the mean of 30.27 ±â€¯2.71 days and 38th day in Group II with the mean of 30.32 ±â€¯3.08. The VAS, KOOS, and WOMAC score improved significantly postoperatively in both the groups. CONCLUSION: The difference between the two methods of fixation was statistically insignificant. Fixator-cum-distractor is minimally invasive giving good control over the final limb alignment; however, it is cumbersome with less patient compliance and has complications like pin tract infection. Locking plate provides better fixation stability than fixator-cum-distractor even without bone grafting; however, it is an invasive procedure requiring more soft tissue exposure and precise amount of wedge removal.

Radiological protocol in spinal trauma: literature review and Spinal Cord Society position statement.

PURPOSE: The Spinal Cord Society constituted a panel tasked with reviewing the literature on the radiological evaluation of spinal trauma with or without spinal cord injury and recommend a protocol. This position statement provides recommendations for the use of each modality, i.e., radiographs (X-rays), computed tomography (CT), magnetic resonance imaging (MRI), as well as vascular imaging, and makes suggestions on identifying or clearing spinal injury in trauma patients. METHODS: PubMed was searched for the corresponding keywords from January 1, 1980, to August 1, 2017. A MEDLINE search was subsequently undertaken after applying MeSH filters. Appropriate cross-references were retrieved. Out of the 545 articles retrieved, 105 relevant papers that address the present topic were studied and the extracted content was circulated for further discussions. A draft position statement was compiled and circulated among the panel members via e-mail. The draft was modified by incorporating relevant suggestions to reach a consensus. RESULTS AND CONCLUSION: For imaging cervical and thoracolumbar spine trauma patients, CT without contrast is generally considered to be the initial line of imaging and radiographs are required if CT is unavailable or unaffordable. CT screening in polytrauma cases is best done with a multidetector CT by utilizing the reformatted images obtained when scanning the chest, abdomen, and pelvis (CT-CAP). MRI is indicated in cases with neurological involvement and advanced cervical degenerative changes and to determine the extent of soft tissue injury, i.e., disco-ligamentous injuries as well as epidural space compromise. MRI is also usually performed when X-rays and CT are unable to correlate with patient symptomatology. These slides can be retrieved under Electronic Supplementary Material.

Demographic Study of Orthopedic Trauma among Patients Attending the Accident and Emergency Department in a Tertiary Care Hospital.

BACKGROUND: Trauma causes a major burden on the health system and economy of the country. A better understanding of the epidemiology of trauma can be of great help in planning preventive and curative strategies. MATERIALS AND METHODS: A total of 4834 patients of trauma presenting during 1 year were included in this observational study. Demographic profile and other related criteria were noted, and data were statistically analyzed. RESULTS: Male to female ratio was 5:1; most affected age group was 25-44 years in males and 45-64 years in females; 23.2% were illiterate; and professionals and students were most commonly affected. Road traffic accident (RTA), fall, and assault were the three most common causes; two wheelers were the most common accident causing vehicle. Nearly 17.7% were below poverty line and 67.6% reached hospital within 12 h. Medicolegal cases were 29.7%; only 29.3% reached hospital by ambulance and 3.72% were hemodynamically unstable. Only 3.6% received prehospital care and 16.23% were under alcohol influence. About 23.18% of RTA victims were pedestrians; city roads were the most common accident site. Head injury (25.85%) was the most common associated injury. Fractures were most common in hand (9.72%). The injury severity score (ISS) and New ISS were worse in the patients who were not using seat belt/helmet or were under influence of alcohol. The rate of death and associated injuries was also higher in this group. CONCLUSION: Trauma is a major preventable cause of mortality and morbidity mainly affecting the productive age group of the society.

Evaluation of results of open distal femur fractures with primary fixation and antibiotic impregnated collagen.

PURPOSE: Distal femoral fracture is one of the most common lower limb injuries and accounts for less than 1% of all fractures. Open fracture takes 5%-10% of the all distal femoral fractures, which is at an increased risk of complications. There were limited studies which documented the outcomes of such cases. The present study aims to evaluate the outcome and complications in these fractures using primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to aggressive debridement. METHODS: This is a prospective study conducted in a tertiary care orthopaedic hospital in northern India. Thirty patients of open distal femoral fractures were managed by primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to aggressive debridement. They were followed for minimum of six months. Patients were followed up monthly for first four months, at six months and one year after surgery. Clinical and radiological signs of healing, any complications, time to union, and functional outcome were assessed. RESULTS: The mean age of patients was 44.33 years (range 20-82 years) with male predominance of 66.7%. According to Gustilo-Anderson classification, there were 5, 15 and 10 patients with open grade I, II and IIIA distal femoral fractures respectively. According to orthopaedic trauma association (OTA) classification, majority of patients in our study were of C3 type. The mean time to bony union was 5.6 months (range 4-9 months). Average postoperative knee range of motion (ROM) at the latest follow-up was 98° (range 70°-120°). Lysholm knee scoring scale showed excellent score in 11 patients, good in 9 patients, fair and poor in 5 patients each; however, there was no significant correlation with fracture pattern types (p < 0.05). Knee stiffness was the major complications encountered in the study. The knee ROM was <90° in 5 patients and 90°-120° in rest of the patients, while 1 patient had extensor lag of 10°. One patient had implant failure and lost to follow-up; 3 patients had deep infection. CONCLUSION: An approach of primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to early aggressive debridement in open distal femur fractures shows significant results in terms of functional and radiological outcomes with minimal complications.

Prospective randomized comparison of quality of regenerate in distraction osteogenesis of ring versus monolateral fixator in patients with infected nonunion of the tibia using digital radiographs and CT.

AIMS: In this randomized study, we aimed to compare quality of regenerate in monolateral versus circular frame fixation in 30 patients with infected nonunion of tibia. PATIENTS AND METHODS: Both groups were comparable in demographic and injury characteristics. A phantom (aluminium step wedge of increasing thickness) was designed to compare the density of regenerate on radiographs. A CT scan was performed at three and six months postoperatively to assess regenerate density. A total of 30 patients (29 male, one female; mean age 32.54 years (18 to 60)) with an infected nonunion of a tibial fracture presenting to our tertiary institute between June 2011 and April 2016 were included in the study. RESULTS: The regenerate mineralization on radiographs was comparable in both groups at two, four, six, and ten months' follow-up but the rail fixator group had statistically significant higher grades of mineralization when compared with the circular frame group at eight and 12 months' follow-up. The regenerate mineralization was also higher in the rail fixator group than in the circular frame group on CT at three and six months, although this difference was not statistically significant. CONCLUSION: Overall, the regenerate mineralization was higher in the monolateral than the circular frame group. A monolateral fixator may be preferred in patients with infected nonunion of the tibia with bone defects up to 7 cm. Cite this article: Bone Joint J 2019;101-B:1416-1422.
